The tiny, round island of Nisyros is one of the most fascinating islands of the Dodecanese and a UNESCO Global Geopark, recognized for its exceptional volcanic landscape and geological heritage. With just four villages, Mandraki and Pali on the coast, and Emporeio and Nikia perched on the slopes of the volcano’s caldera, it feels worlds away from the larger islands. In the morning, we’ll take a boat from Kos to Nisyros and, upon arrival, transfer to the whitewashed village of Nikia, perched dramatically on the edge of the island’s 4-km-wide caldera. From here, we’ll hike down towards the floor of the caldera and into Stefanos Crater, the largest and most impressive of Nisyros’ volcanic craters. Walking inside an active volcanic crater is a truly unique experience; with its steaming vents, barren landscape and striking mineral colors, the scenery feels almost otherworldly. After exploring Stefanos Crater, we’ll drive back to Mandraki, the island’s charming main village. Here, we’ll take some time to explore its narrow streets, traditional whitewashed houses and waterfront before sitting down for lunch at a local taverna. After lunch, we’ll return to the port and catch the boat back to Kos, arriving in the afternoon.
